Raid employs many active ingredients, including tetramethrin. Tetramethrin is a synthetic insecticide that works by attacking the nervous system of most insects. Once the insect comes into contact with the insecticide, it breathes it in causing quick damage to the nerves leading to death.
The second active ingredient in Raid products is pyrethrin. Pyrethrin is also a pesticide that targets the nervous system of insects. When used in small amounts it can be used as an effective nonlethal repellent. However, in Raid products, it is used in doses high enough to bring death to insects.
Piperonyl butoxide is another active ingredient in Raid. Unlike pyrethrin and tetramethrin, piperonyl butoxide is not an insecticide. It is however, a synergist to the insecticides in Raid. What this means is that piperonyl butoxide increases the effects of the insecticides themselves. Piperonyl butoxide works by retarding the insects' internal detoxification systems, allowing Raid to stay inside the insect for longer periods of time without being metabolised out of the body.
Raid also kills bugs by the way it delivers its products. Each type of Raid product has similar ingredients, however, the way in which the ingredients are delivered to the insects vary. For example, Raid for wasps and hornets uses a high pressure delivery system that allows the user to stand far enough away to not be stung by the insects once the product is delivered. Other delivery methods include foggers, aerosols and sprays.
